You did ask about having the flipcharts on the laptop, which allows people to access those when they are not on the school network.. So I guess you don't actually want them in the Shared drive on the server?
I encourage people to save resources that are additional to the ActivInspire Shared Library (the installed files PLUS the Subjects folder..) into My Library, which should be on the local drive in the computer. This 'common' set of resources can easily be replaced, unlike a user's personal collection.
Users can easily add a folder to their My Library specifically for that collection of flipcharts, and it will be accessible using the Inspire Resource Browser.
Hope this helps.
